Cylinder classification

The type of cylinder and the application in which it is used are two of the main criteria when selecting the appropriate seals and guides. Applications are referred to as light duty, medium duty or heavy duty applications. These classifications are somewhat subjective but the duty levels are typically characterized by the following criteria.

Light duty cylinders

Light duty cylinders, e.g. cylinders used for stationary equipment indoor in a factory environment, may be characterized by:

system pressures up to 160 bar (2 300 psi)

temperatures up to 70 °C (160 °F)

rare pressure peaks in excess of system pressure

minimal side loads acting on guides

environment with moderate temperature fluctuations and relatively free of contaminants
